Configuring Mobility Groups

Prerequisites

Before you add controllers to a mobility group, you must verify that the following requirements have

been met for all controllers that are to be included in the group:

• All controllers must be configured for the same LWAPP transport mode (Layer 2 or Layer 3).

Note You can verify and, if necessary, change the LWAPP transport mode on the Controller >

General page.

• IP connectivity must exist between the management interfaces of all controllers.

Note You can verify IP connectivity by pinging the controllers.

• All controllers must be configured with the same mobility group name.

Note The mobility group name is generally set at deployment time through the Startup Wizard.

However, you can change it if necessary through the Default Mobility Domain Name field

on the Controller > General page. The mobility group name is case sensitive.

Note For the Cisco WiSM, both controllers should be configured with the same mobility group

name for seamless routing among 300 access points.

• All controllers must be running the same version of controller software.

• All controllers must be configured with the same virtual interface IP address.

Note If necessary, you can change the virtual interface IP address by editing the virtual interface

name on the Controller > Interfaces page. See Chapter 3 for more information on the

controller’s virtual interface.

Note If all the controllers within a mobility group are not using the same virtual interface,

inter-controller roaming may appear to work, but the hand-off does not complete, and the

client loses connectivity for a period of time.

• You must have gathered the MAC address and IP address of every controller that is to be included

in the mobility group. This information is necessary because you will be configuring all controllers

with the MAC address and IP address of all the other mobility group members.

Note You can find the MAC and IP addresses of the other controllers to be included in the mobility

group on the Controller > Mobility Groups page of each controller’s GUI.
